Docker image doesn't find the path to make work a cmd bash.sh file - docker

Question

I have built a Docker image which calls a bash file and processes some files in a specific folder, but I can't manage to make it run/work. I have tried different approaches but cannot find where the issue is. Building an image with
docker build -t user/mycontainer .
works, but the bash script doesn't run when I
docker run mycontainer `pwd`:/app
Instead it produces an error:
docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "/path/c/to/where/i/run/teh/docker:/app": stat /path/c/to/where/i/run/teh/docker:/app: no such file or directory: unknown.
When I run docker ps there aren't any containers, but if I docker ps -a the container just built appears.
I try running
docker exec -it <container id build> bash
and I get a different error response from daemon:
Container <container id build> is not running
The docker image seems to build all the dependencies and the bash code works when run it separately in my local within the folder.
My dockerfile looks:
FROM alpine:latest
# Create directory in container image for app code
RUN mkdir -p /app
# Copy app code (.) to /app in container image
COPY . /app
# Set working directory context
